AJPJFARATUS FOR PRINTING AND CDPYJING MUSIC AND THE LJIK.

Application led March To all whom t ma@ oofncewt:

Be it known that l, THOMAS WALTON, a subject of the King of Great lBritain and Ireland, and residing at St. Andrews' Vicarage, Short Street, New Cut, Lambeth, London, S. E. l, England, have invented a certain new and useful llmproved Apparatus 'for Printing Iand Copying Music and the like, of which the following is a specification.

This invention relates to typewriting machines and has for its object to p-rovide a simple and compact form. of machine capable of reproducing a relatively large number of characters such 'as is required, for example, in the case of music or a number of oriental languages, it being obvious, however, that the invention may be applied wit-h equal effect and like advantage in any case where it may be desired. to utilize a large number of characters' without unduly increasing the size and complexity of the machine.

'llhe invention consists in a typewriter comprising a type magazine or carrier having a plurality of supporting holders or rows of type, each of which contains a separate set of type carriers, means comprising two sets of keys, one set of keys for positioning the holders or rows and a second set of keys for vpositioning any particular type in the selected holder or row in the printing position in relation to the paper o-r other Ina-- terial upon which the prin-ting is to be eftected.

The invention also consists in a typewriter as set out inthe preceding paragraph having in combination there-with means for holding the papenor other sheet to be printed upon, key-operated means for selecting any particular'type row from the magazine or carrier and secondary` key-operated means for bringing the selected type' or the selected row into printing relationship with the paper or other material on which printing is to be effected.

rlFhe invention further consists in a-=typewriter as set out in the penultimate paragraph, havingin combination therewith means for holding the paper or other sheet to be printed upon, primary key-operated means for selecting any `particular holder or row and secondary key-operated means for bringing the selected type or the'selected holder or row into printing relationship with the paper or other mate-rial on which printing is to be effected.

The invention still further consists in apparatus as set out in the penultimate para` graph in which the type magazineor carrier, holder or row is movable relatively to the selecting device to enable any particular type to be selected for conveyance to the printing position.

. My invention will now be described with reference to the accompanying drawings, in which:

Figure l shows a front view of one form of construction;

Figure 2 'shows a ure l;

Figure 3 shows a plan, a art of the upper mechanism being removed or clearness;

Figure 4 shows somewhat diagrammaticallly another lform which my invention may ta e;

Figure 5 shows the type bar tray; Figure 6 shows a carrie-r for saine; Figure 7 shows an end view of the inking device as shown in Figure 4; and

' Figure 8 shows an alternative methodofv tye gripping device. f f f' eierring now to Figures l, 2 and '3, l[' forinmy improved machine with 'a cylindrical typevbar holder l of sufficient dimensions toaccommodate the maximum number of type characters; and such type characters-may either be formed upon the cylinv drical surface or they may be separate therefrom-and arranged in slots, guides or other devices provided upon the surface of the cylinder, the arrangement being such that the cylinder 1 comp-rises a plurality of rows parallel with the axis of the cylinder, each row comprising a plurality of types. The cylinder l is adapted to be rotated by a toothed quadrant 2 controlled bysprings 3, 3, t-he said quadrant engaging a spur wheel 4 on the spindle 5 upon which the Cylinder 1 is mounted, said spindle and cylinder being carried in suitable bearings 6 'provided upon the base 7 of the machine. ln conjunction with'the said spring controlledv quadrant 2 I provide a number of keys 8 corresponding in number to the number of rows of types upon the cylinder l, keys 8 being connected with the cylinder operating mechanism by means of links 8a adapted to operate bell crank levers 9 mounted upon suitable bearings 10, the construction being such that on 4side elevation of Figa particular key being depressed the cylinder 1 is rotated to bring the corresponding type into printing relationship with the paper or other material to be printed on provided upon the carriage 15.

The keys 8 are'mounted upon levers 16 having `a common pivot 17 and arev each adapted to be depressed through a definite predetermined distance, a fixed comb member 18 being provided for this purpose, having slots 19 through which the key levers 16 are each adapted to move when operated.

The key levers 16 are arranged to rest transversely upon pivoted levers or tracker bars 22, 23, said bars being fulcrumed at their outer extremities 24, 25 respectively, the arrangement being such that the extremity of one or the other of the pivoted levers or tracker bars 22 or 23 will be depressed through a definite distance, depending upon the distance of the key lever from the fulcrum of the tracker bar of any one of the keys being operated.

This movement of the extremity of one or the other of the pivoted tracker bars 22 or 23 resulting from the operation of a particular key will be communicated through member 8"L to either one or the other of the bell cranks 9 'which in turn will cause the type cylinder l to be rotated in one direction or the other dependent upon the particular tracker bar operating, the necessary rotary movement being obtained through link 26 or 27 operating either the member 28l or 29 which in turn rotates the cylinder l through arm 30 or 31, segment 2 and spurwheel 4, so that the particular row of types corresponding to the particular key depressed or operated will be moved into the printing position in relation to the paper 28 or other material provided upon thecarriage 15, and upon which the printing is to lbe effected.

For the purpose of bringing any particular type in the selected row into the printing position in relation to the printing hammer or striker or other device I provde a second series yof keys 32 also provided with tracker bars 35 and 36 and comb member 38, the object of this supplementary set of keys being to cause the carriage 15 to be moved laterally in relation to the cylindrical type holder 1 by means of one or the other of the bent bars 40 or 41 pivot ed to the base of the machine at 20 and 21 and adapted to operate by engaging one or the other of the rollers 33 or 34 mounted upon the base of the carriage 15, whereby the latter is adapted to be moved laterally, the amount of such movement being dependent upon the' particular key actuated to` operate either one of the tracker bars and consequently either of the bent levers 40 or 41; the printing hammer or striker 40a being brought into position for striking against the particular type selected, and being preferablyl actuated by a separate key 42 provided for this purpose and operating in the following manner:

Attached lto the outer extremities of the key 42 are two rods 44 and 45 slidably mounted on pillars 46 and 47 provided on the base of the machine, the rods 44 and 45 being adapted to be depressed by the act of operating the key 42 against the springs provided in the said pillars, whereby the key 42 tends to return to its normal position after being operated. The key 42 is further provided with a centrally located rod 48 adapted to actuate a lever 49 pivoted at 50 in such a manner that its end remote from the rod 48 will function to rotate the member 52 pivoted at each of its extremities 53 and 54 to the base of the machine. The face 56 of the member 52 thereupon engages with the hammer arm 58 to operate the hammer or striker 40L attached to the carriage 15, the member 52 being of such a length that it will engage the hammer arm 58 when the carriage is in any position relatively to the type carrying cylinder.

The act of operating the hammer arm 5S also gives relative vertical movement to the paper or other material to be printed upon which is carried upon the carriage l5, by raising the link G0 and roller 63 to operate the pawl 61 and ratchet wheel 62, variable spacing being effected by varying the posi tion of the roller 63 inthe slot 64, further manually operated spacing means being provided at the extremity of the paper carrying roller if found desirable, the spacing being in the vertical direction when the machine is required for Chinese in which the lines are vert-ical and not horizontal.

After each printing operation the carriage 15 is adapted to be returned to its ccn tral and normal position by means ot' springs 65 and 66, the carriage being further provided for this purpose with a positioning pin 64 working against the action of a spring 67 to engage a recess in a fixed part of the machine whereby such position may be more readily maintained. lf found desirable the helical springs 65 and 66 may be replaced by volute springs or other similar means.

If desirable the machine may be provided with a number of indicating strips 7() and 71 as shown, having type characters thereon corresponding with the type characters upon the cylindrical holder 1, such indicators being actuated by rotation of the type selecting keys and effected by means of racks and pin'ions, worm and worm wheels, or other devices operated by the rotation of the cylinder for'the selection of any particular type row.

llO

"'such that the operation of depressin neas, ioe

lin the construction shown, movement of the strips is effected by means of annular toothed wheels 72 and 73 provided upon the outer surface of the type carrying cylinder 1, said annular wheels driving wlth pinions 74 and 75, provided with bevel wheels 76 and 77, engaging with bevel pinions 78 and 79 uponthe spindles 80 and 81, the spindles 80 and 81 having mounted upon their extremities remote from the bevell gears, small pulleys 82 and 83, provided if necessary with bands upon their surfaces adapted to engage holes provided in the sides of the indicating tapes 70 and 7l whereby the latter are adapted to pass over the said pulleys, the arrangement being any particular key to rotate the cylin er to bring the selected row of type into operative position causes the particular symbols in that row to be indicated on the tape beneath its correspondingkey upon the series of keys 32.

The key bars 32a and 32b are connected with the stationary shaft 32c on which they are pivoted and are provided with box shaped members Sli and 85 enclosing the pulleys 82 and 83.

'Where an ink ribbon or similar inking device is employed (not shown) the paper may be protected if necessary by a sheet of celluloid 87 or similar material provided on the face of the carriage as shown, the celluloid or other stri having a suitable aper-A turey through which the hammer l0a may operate.

llf necessary the types may be fastened to the cylinderby means of screws or similar means, in such a manner as to be readily removable therefrom.

Assuming, for example, that the type holder has 108 rows of types with .72 types in'each key it will be seen that the machine is capable of printing 7 ,77 6 characters with the use of only 180 keys, and the over-all dimensions of the machine may be made relatively small having regard to the large number of characters which may be obtained. y

ln the form of the invention illustrated in Figs. 4t to 8 the improved apparatus includes a base plate 90 upon which is movable laterally a. carriage 92 while operatively associated With the carriage and the base plate is a roller 93 which carries the paper or material to be impressed the paper being thusenabled to be trained from' the roller to the upepr part of the carriage 92 fora purpose that will hereinafter appear.

A type carrier 94 is arranged to operate beneath the base late 90 and comprises endlessbands 95'which rotate over pulleys 96 and 97 such pulleys being provided at each end of the/machine and are-connected .together by common shafts, the endless bands 95 having suspended thereon by rollers 112. 113 in a manner lso as to be-readily movable any desired number of holders v98 for accommodating rows 0f type bars-99 the latter being adapted' to be removedfrom the holders and in turn may have three or other number of characters formed thereon.

loc-king plate is also provided in conjunction with 'each holder or tray, the arrangement being such that a slight lateral movement of the locking plate will be sulicientl to release the type bars from their locked position on the holder when the latter is in its functional position.

In general it will be convenient'to arrange.

in eacha holder or tray those types or charadapted to be depressed through a. definite predetermined and uniform distance. A tracker bar 104 is also provided and is suitably located beneath the member' 101 such tracker bar being capable` of a varying' vver- /tical movement depending upon the particular key and its lever which may be operated. rllhe varying movement imparted to the tracker bar is communicated by means of bell cranks 105 to pitmans 106 located on the upper part of the base at the opposite sides thereof, the outer extremities of the pitmans 106 being pivotally connected to the 1 arms of spring controlled segments 107. lt is to be appreciated that when the tracker bar104 is depressedand the bell cranks swung about their pivots a rectilinear movement will be imparted vto the lpitmans 106 to rock the segments 107 and as the segments are in engagement with pinions 108 on the shaft which supports the pulley 97 this movement will act to actuate the type carrier and thereby bring a particular type holder or tray into a predetermined position so that it may be removed therefrom by hand. llt is to be noted that the carriage 92 is formed at its forward .end with a receivtioned howeverthat the synchronous 'movement to ensure of the operation of the indileating tapes `136 is effected by the provision of an additional gearwheel 134 on the axis of the roller 93 said gear being in mesh withtlie teeth 133 on: the pulley vwheel 9]? and they are also inmesh with the pinions 135. A spring chuck 12() is mounted in a casing and is positioned so as to receive the particular type bar 99 from the selected holder or tray 98. The casingrests in a horizontal position on a stud 121. The opposite end of a casing 122 is swingably connected by a sutable bell crank-'lever to abracket on the Jsupporting base.

' the particular selected type bar vwill be swung upwardly so as to -effect a character impression on the paper or other material not shown which is adapted to be arranged in advance of a platen 131. lSubsequent to this action the spring controlling the plunger 125 causes the casingto be returned to its original position andthe type bar removed therefrom.

ln conjunction with the type tray receiving portion 114 at the front part of the carriage 92 suitable inking mechanismsuch as indicated by the numerals 140 and 142 in Fig. 7 may be employed and `in the present instance comprises generally an inking roller 140 which is connected. toa'n` adjacent bell crank 105 and .is adapted to distribute inkA over the types in the selected holder or tray.l In Fig. 8 there vis illustrated va slightly modified form of chucks 147, 148 and 149 for engaging the selected type-bars l145 and 146.

It will be seen that withv such an appai ratus as herein described that itis possible to produce a very compact and comparatively simple form of machine capable of employing a large *number of characters without making the. machine unduly lcompleX, as for example assuming that the machine has keystand 24l1olde'rs or trays in the type carrier each holderwill Vcontain 60 type bars and if each' type bar has three -characters thereon the total number of characters which'can .be reproduced lwith the 60 keyson the machine is 60 3 v 24=4320- It I a further detailed description o fthe tion of theinven'tionis unnecessary."

will be understood however that these figures are given merely by way of example sin'ce other ratios of thenumber ofv characters reproducible to the number of keys adopted may be obtained by sutableigvariations. in

the vdesign ofthe machine. ,l l y It is believed in view of the foegoing that wise: it is believed thatfthe advantagesfof the invention will be readily-apparent.

i f ff" tion a type carrier, a plurality of rows of V types thereon, means for holding the material upon which characters are to be impressed, actuating means comprising two sets of keys, one set of keys acting to position the rows and the other set of keys acting to select any particular type in the selected row for character impression and the type carrier being movable relatively to the selecting keys to enable any particular type to be selected for conveyance to the character impression position.
